Hi Dave and Matt,

 

I went back and found the link to the information.
http://www.ligo.caltech.edu/docs/P/P070054-00.pdf  I think you are both
correct. 

 

I can see these techniques being useful in Geoff's 3 dimensional seismometer
in that strict calibration in multiple degrees of freedom would not be
required.  Scaling and noise reduction could fall in the interface of the
model with the sensed response.
